Ammitzbøll G, et al. – In this study, researchers investigated whether progressive resistance training (PRT) after breast cancer (BC) surgery can prevent arm lymphedema (> 3% increase in the interlimb volume difference by water displacement). Study participants included women aged 18-75 years who were undergoing BC surgery with axillary lymph node dissection. Using computer randomization, participants were allocated to either an intervention group (PRT 3 times weekly: as a supervised group exercise in the first 20 weeks and as a self-administered exercise in the last 30 weeks) or usual care group. Arm lymphedema in the first year following BC was not prevented by PRT; however, resistance training was confirmed as a significant and safe option for patients, including women at high risk for lymphedema.
